What new or enhanced feature are you proposing?
Wait N seconds after a comment is submitted before sending notification emails, to give a chance to Delete the comment.
What goal would this enhancement help you achieve?
When I post a comment, I sometimes realize after clicking "Submit" that I've made an error. The only way to correct it is to delete the comment and repost.
Doing that, though, sends a total of 2 notifications to Starred and CC members. Spam sucks!
Delaying the notification for, say, 30 seconds would give time to delete the comment and avoid the spam.
If you have data on how long people tend to wait after posting a comment to delete it, that would inform this decision. If 50% of "comments deleted by author" are deleted with 30 seconds, that might be a good cutoff. If most are deleted after 24 hours, then this request is a WontFix :)
